Hi! My friend is a licensed nail tech and I agreed to help her with a soul project she has - she want to start her own line of professional products (small at first some builder gels, acrylic powders etc) but she wants to make them available only for licensed professionals only (I'm doing her website and design materials). She wants to have international shipping but we have no idea how to check who has a license and who does not for countries outside of US - UK for example. Do you have any thoughts or any ideas on how we could make this happen? And do you have any idea how other brands do it? Any help is appreciated! thank you and have a blessed day!
